Yes, it's common for PhysX to impact performance on a GTX 970.

I need to disable PhysX entirely in every game that supports it, since it often causes noticeable performance issues. Is this typical?
It causes the card to load significantly more, though I think the issue isn't from the physics work itself. It's likely because of the extra mesh and objects it needs to render for PhysX to function properly.
That's correct, in recent titles with PhysX compatibility I run my GTX650ti as a specialized card.
